Papers by Keyword: H. Rietveld Analysis

Abstract: The atoms site preference in the Al₃Ti-Zn system has been studied using H. Rietveld method. The L12 Ti(Al, Zn)₃ particles evolve in a ZnAl25 melt from the L1₂TiZn₃ particles in the ZnTi4 master alloy. It is found that Zn is replaced by Al during the transformation TiZn₃ → Ti(Al, Zn)₃. In the evolving fcc L12 Ti(Al, Zn)₃ phase Ti occupies (0, 0, 0) position while Al and Zn occupy (0, 0.5, 0.5) position, similarly to Al and X in the Al₃Ti-X systems, where X = Ni, Cr, Mn, Cu, Ag, Pd [1, 2].
